Nothing related to sex is one-size-fits-all! Your experience with Eva II
depends on your anatomy and how you like to have sex.
We designed Eva to provide a comfy fit for a wide variety of people with vulvas, and refined that design until a strong majority reported it stayed secure in most positions.
Our testing shows that Eva’s compact size and conforming shape make it a step-up from a bullet or other vibrator, even when it needs a little help to stay in place. Because Eva's wings do most of the work, pressure between bodies or from a finger can do the rest.
